Application example: "Seawater desalination: Reverse osmosis membrane filtration (RO method)"

Application example: "Seawater desalination: Reverse osmosis membrane filtration (RO method)"

Proposal for seawater distribution valve

Reverse osmosis (RO) is a seawater desalination method that reverses the natural process of osmosis and consumes less energy compared to distillation. High pressure (5.5 to 8 MPa) is applied to seawater, allowing only water molecules to pass through a semipermeable membrane while blocking dissolved salts. The water that passes through can be used as drinking water.

Application Example: "Seawater Desalination: MSF Method (Multi-Stage Flash Method)"

Application Example: "Seawater Desalination: MSF Method (Multi-Stage Flash Method)"

Proposal for the water supply valve to the evaporation chamber.

The MSF method (Multi-Stage Flash Distillation) is a seawater desalination method primarily adopted in places where surplus steam can be used as a heat source. The feedwater is heated in several stages. The brine passes through a series of evaporation chambers where the pressure gradually decreases. The generated steam is condensed in a heat exchanger to produce drinking water while simultaneously preheating the incoming seawater. The water that has gone through the final stage is sent to the next treatment process.

Application Example: "Seawater Desalination: MED Method (Multi-Effect Distillation)"

Application Example: "Seawater Desalination: MED Method (Multi-Effect Distillation)"

Proposal for a water supply valve for the heat transfer pipe.

The MED method (Multi-Effect Distillation) is a seawater desalination process that utilizes the surplus heat from adjacent power plants and evaporates under progressively increasing negative pressure. The feedwater is repeatedly sprayed into heat exchange tubes that are heated from the inside by condensing steam through several stages. After evaporation, the water is condensed in the heat exchange tubes of the next chamber, and the latent heat is recovered. The distilled water obtained in this manner is extracted from the system.

Application example: "Purified Water and Ultra-Purified Water Production: Water for Injection (WFI)"

Application example: "Purified Water and Ultra-Purified Water Production: Water for Injection (WFI)"

Proposal for a valve for supplying injection water (WFI).

The production of water for injection (WFI) uses multi-purpose can-type and thermal compression distillers according to the required amount and temperature of distilled water. The "thermal compression" method pressurizes the generated steam using a heat pump, raising the temperature from 100°C to 140°C, and utilizes it for heating the supply water. We offer diaphragm valves specifically developed for use in ultrapure water treatment and supply equipment as well as process equipment.

Application example: "Solvent Supply"

Application example: "Solvent Supply"

Proposal for valves for solvent supply systems.

In the semiconductor industry, organic solvents are used for the dissolution and cleaning of materials. The solvents used for cleaning are particularly corrosive and difficult to handle, so valves are required to have high chemical resistance. GEMÜ offers a range of products that combine high Kv values and chemical resistance. To maintain purity, the products are generally made of stainless steel and PFA.

Application example: "Supply of slurry"

Application example: "Supply of slurry"

We propose valves that are optimal for handling abrasive slurries.

The handling of slurry can be divided into three main steps: - Adjustment and mixing - Supply and transport - Removal and recovery GEMÜ products are designed with a low-resistance sheet shape that does not impose a load on both the valve and the fluid. All materials in contact with the fluid are made of PTFE or PFA, providing sufficient chemical resistance and high durability against the abrasiveness of slurries containing abrasive particles.
